## What reviewers say

**Bontrager Flare RT** — Two whitelisted cycling outlets tested this exact rear light hands-on and both rate it highly: DC Rainmaker (in-depth review, weighed on his own scale, ran a battery-depletion test) and Cycling Weekly (Editor's Choice, ridden through a wet winter). Praised for its tiny strawberry-sized form factor, weatherproofing and Garmin/ANT+ auto on-off; dinged for confusing modes, Bontrager's reused naming, and a Garmin control-panel quirk. DCR weighed the unit at 23g sans-mount versus the 32g/33g official figure. Neither outlet ran lab lumen or runtime numbers on the rear unit. (2 sourced reviews.)
